CLEMENT GUERNSEY HARRINGTON, MAPLEWOOD, MISSOURI;

CABLE-HANGER.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed May 20, 1908. Serial No. 433,916.

T 0 all whom it may concern:

Be it known that I, CLEMENT G. HAR- nmeron, residing at Maplewood, Missouri, United States of America, and being a citizen of the United States, have invented certain new and useful Improvements in Cable- Hangers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to'which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limitedto the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a perspective view showing my improved cable hanger in use; Fig. 2 is a transverse section through a cable and supporting wire with the parts locked in position; Fig. 3 is a plan view of the cable hanger extended showing in dotted lines the extension which is folded back as hereinafter described; and Fig. 4 is an edge view in full and dotted lines.

The object of the invention is to produce a cable hanger which can be made cheaply, can be easily put up and fastened in position without making any sharp bends therein, and which can be easily taken down without the aid of special tools. To that end a flat metal band A. of some flexible metal is used which is folded back upon itself at one end as shown at A so as to stiffen this portion of the hanger and permit it to be folded into the form of a hook as C, whereby it may be suspended from a supporting wire or cable E.

Relatively just below the hook C is a perforation 2 which extends through the metal portions AA and beyond this the metal strip extends as indicated in the drawings being slightly reduced near its opposite end and has connected therewith an engaging member B which is secured by means of a headed rivet 3 or other equivalent means to the strip A, the member B extending beyond the end of the strip so as to allow it to be projected through the perforation 2 as best shown in Fig. 3 to lock the cable hanger thus formed in position and support the cable D.

It will be observed that the locking member Bis formed of a resilient material and preferably of spring wire with shoulders 4 adapted to engage with the metal surrounding the perforation 2.

By forming the hook C in the manner shown it is evident that said hook portion is relatively rigid, whereas the remaining portion of the hanger is sufliciently ductile to permit it to be wrapped about the cable D and readily secured in position.

To hook up the cable D after the hook C is caught on the supporting cable or wire E, the flexible metal band A is bent around the cable D and the spring catch B is forced through the opening 2 just under the supporting wire E. When this engaging member is passed part way through the perforation 2 the shoulders 4. will be separated and will become locked in position. When in this position the hook portion C will not become accidentally disengaged from the wire E, as spring catch B will prevent such disengagement.

To take down the hanger, all that is necessary is to press the arrow points F of the spring catch B nearer together so as to permit them to clear the sides of the opening 2 when the spring catch may be withdrawn thereby releasing the metal band from its position surrounding the cable D.

What I claim is 1. In a cable hanger, the combination comprising a sheet metal suspension hook member with bent and perforated end portion and an expansible locking member adapted to engage therewith.

2. In a cable hanger, the combination comprising a sheet metal member with a rebent hook portion at one end with a perforation therein and a spring metal locking member extending beyond its opposite end.

3. In a cable hanger, the comblnatloncomprismg a sheet metal suspension hook member reinforced near one end by rebending a portion thereof, with a perforation extending through the reinforced portion and a locking member projecting beyond its opposite end, said locking member being adapt-ed to enter said perforation.

4. In a sheet metal cable hanger, the combination comprising a rebent hooked end portion with a perforation relatively below the hook and an expansion locking member extending beyond the opposite end of the hanger adapted to enter said perforation.

5. In a sheet metal cable hanger, the combination comprising a perforated sheet metal strip folded upon itself at one end and the folded portion bent into hook form, a looking member secured near the opposite end of said metal strip and adapted to project 5 therebeyond said locking member comprising an expansible spring hook With shoulders adapted to pass through the perforation in and engage with said folded portion.

6. In a cable hanger or the like, the combination comprising a reinforced hooked end portion With a perforation therein relatively below the hook, a flexible supporting part and a locking member extending beyond this part and adapted to project into said opening to engage the reinforced portion, substantially as described.

7. In a cable hanger, a perforated sheet metal member of single thickness for a portion of its length, having a hooked end of double thickness and a separately formed resilient locking device riveted thereto near the end of the portion of single thickness of metal.

8. In a cable hanger, a sheet metal band having a rebent end portion with coincident perforations therein and an expansible locking member secured near its opposite end, said locking member being adapted to project through said perforations.

In Witness whereof I have hereunto set my hand in the presence of tWo Witnesses.
